I will be testing/improving an spsa tuner at https://github.com/fsmosca/spsa. I am primarily interested on uci engines with settable piece values. Deuterium has and I am looking for others to try. What I will do is to weaken the engine by unoptimizing its piece value and try the tuner if it can imp...

Here is the result for 6s+0.1s How many time forfeits did you get running that timecontrol? I tried reproducing your results with similar conditions and I got a ridiculous number of time forfeits. More than 10%. I ran 5s+0.08 as I have a faster GPU and wanted to be close to your nodes/move. Perhaps...

Thanks! I guess MLH shouldn't change Elo, if Leela was trolling in the endgames without actually missing conversion? But does MLH change the goal from scoring optimization to something like scoring + moves left optimization? That would change Elo. It’s an extra head, so a little bit of a slowdown. ...

I suspect you don’t have MLH turned on. Here are some params: !mlh mlh1 mlh2 mlh3 mlh4 MovesLeftMaxEffect 0.15 0.2179 0.2 0.2 0.15 MovesLeftThreshold 0.3 0.0 0.0 0.0 0.3 MovesLeftSlope 0.01 0.0346 0.007 0.007 0.015 MovesLeftQuadraticFactor 0.85 1.0 0.85 0.0 1.0 MovesLeftScaledFactor 0.0 0.0 0.15 1....

Which version of lc0 and which mlh settings are you using?

v0.25.1 cudnn-fp16
No MLH settings (moves left head, right?). They are not accessible via easy to use UCI settings and I don't know what values to put anyway.

Another badly scaling net from SV, 384x30-t60-4206.pb.gz. All the nets since 3290 LR 0.02 have the same bad scaling. It might explain the current performance in TCEC SuFi, although only 25 or so games were played. 6s + 0.1s Score of SV_384x30_4206 vs SV_384x30_3010: 461 - 352 - 187 [0.554] 1000 ... ...
